WILLIAM DANIELS, OF BROOKLYN, NEW YORK. Lener@ Patent No. 72,373, dated December 17, 1867.

IMPROVEMENTv IN BINDING BOOKS.

TO ALL WHOM IT MAY/OONCERN:

Beit known that I, WILLIAM DANIELS, of Brooklyn, in the county oi` Kings, and'State of New York, have invented a certain new and useful Improvement in Binding Books; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is a view of the fold in the centre leaf oi' a section mafle with my improvement, and

Figure 2 is an enlarged view, sectionrtlly, of tbe leaves of a sect-ion of the book. A

In binding books, particularly blank and account-books, the leaves forming'the respective 'sections are held together by threads running in the fold, and passing out over parchment bands or cords lat the back, and united near the upper and lower parts of the back ,by the kettle-stitchesi The paper of the central vsheet of the section is liable to cut and tear out where the thread passes' out at the upper and lower ends, and the leaves of the section become loose, tearout, and the book is damaged, so that the sheets are liable to tear out and sepnrate from the back. This is particularly the case withl blank and account-books that are frequently handled. If a strip of muslin isadded to the central sheet in the section, to strengthen the same, the thickness of the back is thereby increasefL- Vso that'it does not some-within the space allowed in rounding up the back to allow for the threads that are introduced'in the sewing. v

The nature of my said invention consists in a` strip of muslin applied to the fold of the central sheet ofthe sections of a book, in combination with an opening formed in said sheet at the fold,4 for the reception of the thread used in sewing the book. By this construction, the thickness of the back is not increasedby the introduction of the stri'p of cloth or muslin, because there is a space formed in the paper for thereception'of the thread, which compensates for the additional thickness of 'the muslin or cloth. The central sheet of each section being by this means eihectually secured into place, so'that it cannot become loose or teur out, all the other leaves of the section are by it reliably held in place.

In the drawing, a represents the central leaf ci"` the section; b, the thread used-in sewing the book together;

c, the strip of cloth, attached by suitable paste or cementto the central sheet a, at the fold thereof; and 'i is the space or opening formed in the paper at the fold thereof', in whichthe thread of thc sewing lies, as seen in large size in iig. 2. A

The 4t- Wo thicknesses oi' cloth, which I prcicr to be fine cotton or linen fabric, cut on the bias, are, whenv pressed, only about the same thickness of the thread psu-ally employed; and the long slot or openingr z' in the paper, at the i'old, is suivcient to receive said 'thread-without the thread itself increasing the thickness of 'the` back, because the two thicknesses ot` paper are about equal to the thickness of the thread when pressed. The strip of cloth may be appliedonly at the top and bottom portions of the` sections, or maybe applied all along the fold of the central sheet, the paper being cut out, or forming aslot or opening at those places where the -thread is introduced.

What I claim, and desire to secure by Letters Patent, is

The strip of cloth, applied to`the`fold of the central sheet of the' section of a book, in combination with a long slot or opening in said sheet of paper at the fold, for the reception of the thread used in sewing the book, as specified.

In witness whereof, I have hereunto set my signature, this eighteenth day of December, 1866.

WILLIAM DANI-ELS.
